how would you describe the tone of this book

tone · The narrator never explicitly criticizes Gilgamesh, who is always described in the most heroic terms, but his portrayal of him often includes irony. In the first half of the story, Gilgamesh is heedless of death to the point of rashness, while in the second, he is obsessed by it to the point of paralysis. Gilgamesh’s anticlimactic meeting with Utnapishtim, for example, is quietly ironic, in that everyone involved, including Utnapishtim and his wife, knows more than Gilgamesh does.
